what is the average between (25,28.8,39.2,51.2,64.8,80)? Please help me!
Answers
Answer:
48.17
Step-by-step explanation:
Average = sum of numbers / number of numbers
Sum of numbers = 25 + 28.8 + 39.2 + 51.2 + 64.8 + 80 = 289
Number of numbers = 6
Average = 289 / 6 = 48.17
=>average = 289/6 = 48.167
( since average = sum of observations divided by number observations)

Find the area of the shaded polygon:
Answers
Answer:
6 units squared
Step-by-step explanation:
To solve this problem you can solve for the entire area of the square and subtract the area of the unfilled areas for the area of the shaded region..
Area of entire square is 4*4=16
Now for the sections that are unfilled:
4*3/2= 6
1*1/2= 0.5
2*1 = 2
1*1 = 0.5
2*1/2 = 1
Total area of Unfilled region = 6 + 0.5 + 2 + 0.5 +1 = 10
Area of filled region = 16 - 10 = 6 units squared
Hope this helped!
Write a story that represents the math problem 2/6 times 3/4
Answers
There is only 3/4 of a pie left. Two families decide to split the pie. There are 6 kids total, and they decide that each kid should get a sixth of what's left of the pie. One family has 2 kids, so how much pie will they get?
So 2/6 of 3/4 is 1/4 or .25
step by step: rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 1/4*t6-(-4)=0
simplify 1/4
((1/4•t) - 6) - -4 =0
subtracting a whole from a fraction. rewrite the whole as a fraction using 4 as the denominator :
6 = 6/1 = 6•4/4
equivalent fraction: the fraction thus generated looks different but has the same value as the whole.
common denominator: the equivalent fraction and the other fraction involved in the calculation share the same denominator.
adding up the two equivalent fractions
add the two equivalent fractions which now have a common denominator.
combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
t - (6•4)/4 = t - 24/4
(t - 24) - -4 = 0
subtracting a whole from a fraction
rewrite the whole as a fraction using 4 as a denominator:
-4 = -4/1 = -4•4 / 4
adding up the two equivalent fractions.
t - 8/4 =0
when a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now, to get rid of the denominator. Tiger multiples both sides of the equation by the denominator.
here's how:
t-8 • 4 = 0 • 4
Now, on the left hand said, the 4 cancels out the denominator while on the right side, zero times anything is still zero.
The equation now takes the shape
t-8=0
solve t-8=0
add 8 to both sides of the equation:
t = 8
that's how you get the answer.
Select the correct solution for the expression. 2/5 + 3/8 A. 2/5 + 3/8 = 5/13 B. 16/40 + 15/40 = 31/40 C. 10/40 + 24/40 = 34/40 D. 2/5 + 3/8 = 6/40
Answers
Answer:
B
Step-by-step explanation:
To add 2/5 and 3/8, we need to find a common denominator for the two fractions.
The smallest multiple of 5 and 8 is 40, so we can use 40 as the common denominator.
Multiplying the numerator and denominator of 2/5 by 8, we get:
2/5 = 16/40
Multiplying the numerator and denominator of 3/8 by 5, we get:
3/8 = 15/40
Now, we can add the two fractions:
2/5 + 3/8 = 16/40 + 15/40
Simplifying the numerator, we get:
2/5 + 3/8 = 31/40
Therefore, 2/5 + 3/8 is equal to 31/40.
For five days, Diego recorded the lengths, in minutes, of his walk to school. The mean for his data is 11 minutes. Determine which data set below is Diego’s, and prove that your choice is correct.
Answers
Data Set A: 9, 11, 13, 10, 12
Data Set B: 8, 10, 12, 14, 16
Data Set C: 10, 10, 10, 10, 10
Data Set D: 11, 11, 11, 11, 11
To find the mean, we sum up all the values in each data set and divide by the number of values:
Data Set A: (9 + 11 + 13 + 10 + 12) / 5 = 11 minutes
Data Set B: (8 + 10 + 12 + 14 + 16) / 5 = 12 minutes
Data Set C: (10 + 10 + 10 + 10 + 10) / 5 = 10 minutes
Data Set D: (11 + 11 + 11 + 11 + 11) / 5 = 11 minutes
Comparing the mean of each data set to 11 minutes, we can see that only Data Set A and Data Set D have a mean of 11 minutes. However, to prove that our choice is correct, we need to analyze the individual values in the data set.
In Data Set A, we can observe that the values are relatively close to 11 minutes, with some values slightly above and below. This variation suggests a realistic scenario where Diego's walk to school might take slightly different amounts of time each day.
In Data Set D, all the values are exactly 11 minutes. While it is not impossible for Diego's walk to consistently take exactly 11 minutes each day, it seems less likely than having some variation in the durations.
Based on these observations, we can conclude that the most plausible data set for Diego is:
Data Set A: 9, 11, 13, 10, 12
This data set has a mean of 11 minutes and exhibits a realistic variation in walk durations, making it the most likely choice for Diego's recorded lengths.

What is the area of the region bounded by the graph of the equation x^2+y^2 + 3 = -4y + 6x-1?
Answers
Answer:
9π
Step-by-step explanation:
What we need to do here is convert this equation into a standard circle equation;
x^2+y^2 + 3 = -4y + 6x-1,
x^2+y^2+4y-6x+1 = 0,
x^2-6x+(-3)^2 + y^2+4y+(2)^2 = 3^2
(x-3)^2 + (y+2)^2 = 3^2,
so we have a circle with a radius of 3, and hence the area of our region is π(3)^2 = 9π. correct!

Answers
For Mountain View School:
Data: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 0 + 1 + 2 + 3 + 4 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 8 + 8 + 8 + 9) / 19
= 100 / 19
≈ 5.26
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 0, 1, 2, 3, 4, 4, 5, 5, 5, 5, 6, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
For Seaside School:
Data: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9
Mean: (0 + 0 + 0 + 1 + 1 + 2 + 2 + 4 + 5 + 5 + 5 + 5 + 6 + 7 + 7 + 8 + 8 + 8 + 9) / 19
= 80 / 19
≈ 4.21
To find the median, we need to arrange the data in ascending order: 0, 0, 0, 1, 1, 2, 2, 4, 5, 5, 5, 5, 6, 7, 7, 8, 8, 8, 9.
The median is the middle value, which is the 10th value in this case.
Median: 5
Now let's calculate the measures of variability, specifically the range and interquartile range (IQR).
Range: The range is the difference between the largest and smallest values in the dataset.
For Mountain View School:
Range: 9 - 0 = 9
For Seaside School:
Range: 9 - 0 = 9
Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1) and measures the spread of the middle 50% of the data.
For Mountain View School:
Q1 = 3
Q3 = 7
IQR = Q3 - Q1 = 7 - 3 = 4
For Seaside School:
Q1 = 2
Q3 = 7
IQR = Q3 - Q1 = 7 - 2 = 5
To determine which school is a better choice for a smaller class size, we can consider both the mean and the median.
Both the mean and median for Mountain View School are higher than those for Seaside School. This suggests that, on average, the class sizes at Mountain View School are larger than those at Seaside School. Therefore, if you are interested in a smaller class size, Seaside School would be a better choice
For Mountain View School:
- Median: The median class size is the middle value, which is 25.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (29 + 28 + 28 + 27 + 25 + 24 + 24 + 23 + 21 + 20 + 19 + 18 + 15 + 13 + 10) / 15 = 21.27.
For Seaside School:
- Median: The median class size is the middle value, which is 20.
- Mean: The mean class size is the sum of all the class sizes divided by the total number of classes, which is (25 + 25 + 27 + 27 + 28 + 28 + 28 + 30 + 31 + 35 + 36 + 38 + 40 + 43 + 45) / 15 = 31.13.
Part B:
For Mountain View School:
- Range: The range is the difference between the largest and smallest values, which is 29 - 10 = 19.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 20 and Q3 is 28. Therefore, the IQR is 28 - 20 = 8.
For Seaside School:
- Range: The range is the difference between the largest and smallest values, which is 45 - 25 = 20.
- Interquartile Range (IQR): The IQR is the difference between the third quartile (Q3) and the first quartile (Q1). From the stem-and-leaf plot, we can see that Q1 is 27 and Q3 is 38. Therefore, the IQR is 38 - 27 = 11.
Part C:
If you are interested in a smaller class size, Mountain View School is a better choice for you because it has a lower mean and median class size than Seaside School.

Find and interpret the mean absolute deviation of the data.
Answers
Answer:
The mean absolute deviation is 4
Interpertation: The average distance between each data value and the mean is 4 which is the variation in the data set so you can understand how "spread out" each data point is from each other
Step-by-step explanation:
The mean absolute deviation is a measure of how much a data set varies.
Step 1: Compute the mean
mean = the sum of all the terms / number of terms
mean = 94 + 86 + 95 + 99 + 88 + 90 / 6
= 552 / 6
= 92
The mean is 92
Step 2: Finding the absolute deviation
You would take each number in the data set and subtract it from the mean, take the absolute value. After you take the sum of the absolute data values
|data set #1 - mean| + |data set #2 - mean| + ... + |data set #6 - mean|
= |94 - 92| + |86 - 92| + |95 - 92| + |99 - 92| + |88 - 92| + |90 - 92|
= |2| + |- 6| + |3| + |7| + |- 4| + |- 2|
= 2 + 6 + 3 + 7 + 4 + 2
= 24
To find the mean absolute deviation you divided the sum by total number of terms...
24/6 = 4
The average (mean) is equal to the sum of all the data values divided by the count of values in the data set (which was step 1)
